Ive noticed with the larger turbo my mileage dropped considerably. I was averaging 17+- with AB's and stock turbo, now its anywhere between 13-14 mpg. My big b codes also average 13-14 with the big turbo.For anybody that has actually swapped out splits for some comparable size singles - What kind of changes did you notice, especially on the noise?
What kind of MPG are you getting with the hypermax stage 2 injectors?well, swapped stage 1 singles for a temporary use of stage 2 splits. fuel mileage went way down and power went down as well. this is all with the use of a terminator. Cant wait for the singles to get back!
